BACKGROUND: Limb exoskeletons rehabilitation robots can stimulate the natural resilience of body through simulated human movement to achieve tissue compensation based on its theoretical basis of continued combined active and passive activities.
OBJECTIVE: To dynamically observe and realize the rehabilitation effect of limb exoskeletons rehabili-tation robots on functional exercise of patients with activity limited knee joint.
METHODS: Twenty early postoperative patients with activity limited knee joint were divided into experiment group and control group randomly. The functional exercise with limb exoskeletons rehabilitation robots was performed in the experiment group. The control group underwent functional exercise with passive training devices CPM. Psychological guide, low-frequency pulse electrotherapy and infrared physiotherapy were performed in both groups during the treatment.

Automotive industry, as an important pillar of the national economy, has been rapidly developing in recent years. But proplems such as energy comsumption and environmental pullution are posed at the same time. Electromechanical variable transmission system is con-sidered one of avilable workarounds. It is brought forward a kind of design methods of dualmode electrome-chanical variable transmission system rotational speed characteristics and dualmode drive diagrams. With the motor operating behavior of running in four quadrants and the speed characteristics of the simple in-ternal and external meshing single planetary gear train, four kinds of dualmode electromechanical transmis-sion system scheme are designed. And the velocity, torque and power characteristics of one of the programs are analyzed. The magnitude of the electric splitflow power is an important factor which influences the system performance, so in the parameters matching design, it needs to reduce the power needs under the first mode of the motor. The motor, output rotational speed range and the position of the mode switching point have relationships with the characteristics design of the planetary gear set. The analysis method is to provide a reference for hybrid vehicles’ design. As the involved rotational speed and torque relation-ships are the natural contact of every part of transmission system, a theory basis of system program and performance analysis was provided.
